I have to admit, that I don't quite understand what the inability to create 
signed rsls has to do with the usage of rsls themselves. 

The problem is that the Flashplayer is able to install rsls that are signed by 
Adobe. Usually the Adobe FDK rsls were also available in signed versions (swz 
files). These were dynamically loaded the first time they were needed and 
installed by the Flashplayer. The second time the libs were needed the 
installed versions were used reducing the download time dramatically. Now the 
problem is that Adobe won't sign Apache SWCs as they are no longer in charge of 
the libs code (Understandable). Giving Apache a key to be able to also create 
signed RSLs would eventually open serious security problems because a signed 
manipulated swz would be used by every other website using the same version of 
a given lib.

Coming back to the RSLs ... The difference between a signed and an unsigned RSL 
is just, that the unsigned rsl is loaded on every visit of a user. As far as I 
know there is no other difference. So I don't quite understand why the lack of 
availability of signed rsls should have any effect on built applications and 
the default linking type.

Betreff: RSLs and signing

I did not realize that Apache Flex does not use RSLs by default.

What's the story with signing? Is that an issue with cross-domain security? Is 
there any way to get an Apache signature approved for Flash?

Either way, I'd imagine I'd want RSLs for the simple reason that updating apps 
should result in a smaller download.
